Python学习————作业

今日作业：

1、检索文件夹大小的程序，要求执行方式如下

​ python3.8 run.py 文件夹

import os
import sys

# path=sys.argv[1]
size = 0


def get_filesize(path):
    files = os.listdir(path)
    for file in files:
        if os.path.isfile(file):
            global size
            size += os.path.getsize(file)
        elif os.path.isdir(file):
            get_filesize(file)

2、明天上午日考：随机验证码、模拟下载以及打印进度条、文件copy脚本

随机验证码
import random

n = random.randint(1, 9)


def randomcode(n):
    code = ''
    for i in range(n):
        s1 = chr(random.randint(65, 122))
        s2 = str(random.randint(0, 9))
        s = random.choice([s1, s2])
        code += s
    return code


print(randomcode(n))

进度条
import time


def progress(percent, size=100):
    int(percent)
    res = int(percent * size) * '>'
    print('
[%-100s] %d%%' % (res, 100 * percent), end='')


total = 333333
now_dl = 0
while now_dl < total:
    now_dl += 1024
    percent = now_dl / total
    time.sleep(0.05)
    if percent > 1:
        percent = 1
    progress(percent)

copy
import sys

src_file = sys.argv[1]
dst_file = sys.argv[2]

with open(r'{}'.format(src_file), 'rb') as rf, 
        open(r'{}'.format(dst_file), 'wb') as wf:
    data = rf.read()
    wf.write(data)
